<scp><i>SPAST</i></scp> mutations in <scp>A</scp>ustralian patients with hereditary spastic paraplegia

We conclude that SPAST mutations are responsible for the majority of HSP in Australia. Most of the patients with SPAST mutations had pure forms of HSP and a positive family history to suggest autosomal dominant (AD) HSP. Not all mutations were identified by direct sequencing of the SPAST gene, necessitating further molecular analysis. Given that SPAST mutations cause AD-HSP, these findings are important when providing genetic counselling for affected patients.
